E-mail: gwsmith95@jhmi.edu

Dr. Smith’s research is primarily focused on using functional imaging, particularly positron emission tomography (PET), to understand the regulation of monoamine systems in the pathophysiology and treatment response in affective and cognitive disorders. She is currently examining the role of monoamine dysregulation in geriatric depression and Alzheimer’s disease.
